I recently downgraded from 10.6.4 to 10.6.3 and ever since itunes started to crash and certain times. First it started to crash when i opened it up, so i deleted the library file from my hard drive.(this used to work on windows) after i deleted the file itunes would open up. but now itunes isn't making a new library(wont add songs) and it crashes whenever i open up preferences, i just (as im typing this) uninstalled itunes and dl'ed it again. im only asking now because i feel that this isn't going to fix my problem. similar to installing iWork after using a demo to get it to work properly(i think i have to delete some archive files). i am hesitant to do this without finding out all possible solutions because i do not want to delete a wrong file that messes me up more than i already am. Thanks in advance!
